I've had this in mind for quite a while..., I wanted to mix Google Map and some celestial navigation algorithms to know where the Sun is, and specially to avoid the time when the Sun is right in the direction where I'm driving on the 101, as that makes every car to stop.

Based on Jean Meeus' Astronomical Algorithms, and the great work done by Henning Umland, here is a first drop, available here.

You enter your date (top right panel), and you click on the map.

From the point you've clicked, you should see on the map the direction of the Sun.
